Embodiment Construction

[0015] like figure 1 As shown, the hydraulically opened four-link top cover device includes a compartment 1 that can be installed on the chassis of a vehicle. The rear end of the compartment 1 is provided with a rear door 2 that can be turned over. Compartment 1 top is all provided with positioning block 4 at four corners corresponding top cover, and the lower end of positioning block 4 is fixed on compartment 1 inner side surface, as figure 2 As shown, the upper end of the positioning block 4 is a guide slope, and the top cover turning device is provided on the front and rear outer sides of the compartment 1. The top cover turning device includes a front turning arm 5 and a rear turning arm 6. The shape of the front turning arm 5 is The bent shape can avoid interference with the cab, and the shape of the rear turning arm 6 is a straight rod, which can improve the supporting strength, thereby prolonging the service life and improving safety; the upper ends of the front turnin...

Abstract

A hydraulic opening four-link type top cap device comprises a compartment. The rear end of the compartment is provided with a rear door, the top of the compartment is provided with an overturning top cap, the front and rear sides of the compartment are provided with top cap overturning devices which comprise front overturning arms and rear overturning arms, the upper ends of the front overturning arms and the rear overturning arms are connected with the side edge of the top cap through revolving axles, the lower ends of the front overturning arms and the rear overturning arms are connected with the compartment through revolving axles, overturning oil cylinders are arranged on the outer side of the rear end of the compartment, telescopic rods in the overturning oil cylinders are hinged to the rear overturning arms through joints, overturning positioning blocks are arranged on the side edge of the top cap, the front overturning arms are provided with support blocks at the positions corresponding to the overturning positioning blocks, and after the top cap is overturned through the top cap overturning devices, the overturning positioning blocks and the support blocks are mutually matched to limit the overturned top cap, to make the top cap to be positioned above the cab. The device is simple in debugging, high in reliability, good in stability, convenient to install and use and easy in maintenance.

Description

technical field [0001] The invention belongs to the field of transport vehicles, in particular to a four-link roof device for hydraulically opening. Background technique [0002] In recent years, with the rapid development of my country's economy and society and the acceleration of urbanization, there are more and more heavy-duty trucks "muck trucks" carrying construction waste. Dump trucks randomly throw polluted roads during driving, seriously damaging the urban environment. Due to the serious overloading of muck trucks, the loads on the trucks (mainly stones, soil, construction waste, etc.) The main source of road dust, which seriously damages the road sanitation environment. It is not in line with the establishment of urban civilized traffic demonstration roads. Many muck trucks on the market have no roof or are not tightly sealed, and there is a phenomenon of random throwing when the vehicles are driving, especially for many vehicles to load more goods. The goods exce...
